The Kuju Volcano Group consists of more than ten cones and lava domes NE of Aso caldera. Mimatayama, seen here at the NW side of the complex, has a summit lava dome. The first reports of historical eruptions were in the 17th and 18th centuries when phreatic or hydrothermal activity occurred. Many hot springs and hydrothermal fields are located at the Kuju complex. A fumarole on Hosho lava dome was the site of a sulfur mine for at least 500 years.
